To all whom t may concern:

Be it known that l, DAVID B. KING, a citizen of the United States, residing at Millville, in the county of Cumberland and State of New Jersey, have invented a new and useful Improvement in Bottle or Vial Making Machines, of which the following is a specification.

rlhe principal object of the present invention is to improve the feed of the blanks or sections of tubing to and through the machine in such a way that production is eX- pedited, while at the same time dwells in the feed necessary for the completion of the various operations on the tubes are provided. Another object of the invention is to provide a compact, simple, reliable and comparatively inexpensive machine for making bottles or vials from tubes. Other objects of the invention will appear yfrom the following description and thefinvention itself will be claimed at the end hereof after having been described in connection with the embodiment of it selected from other embodiments for the sake of illustration in the accompanying drawings forming part hereof and in which- Figure l is an elevational view, partly in section, illustrating mechanism embodying features of the invention.

Figure 2 is a top or plan view of parts of the mechanism shown in'fFigure 1, with some of the superstructure removed for the sake of clearness.

Figure 3 is an elevational view, partlyin section, onthe line 3-3 of Figure l. f

Figure l is a perspective view of a portion of the mechanism.

Figures 5 and 6 are views respectively of the cam which actuates the hopper feed and of the cam which controls the mechanism used in the bottoniing operation.

Figure 7 is a view of a tube or blank having at its ends finished portions, and such as is fed tothe machine, and

`Figures 8 to 11 inclusive illustrate steps in the Separation of the tube and in the formation of bottoms on the separated parts.

Referring to the drawings, l is a hopper having an inclined floor and provided with the descent of the blanks toward the outlet of the hopper.v At' the discharge end of the hopper and arranged to receive blanks therefrom are rolls 5, of which eight are shown arranged in pairs, these rolls being positively driven as by means of gearing 6, indicated in dotted lines, from a drive shaft 7, to which power is applied. Associated with the central space between these rolls is a burner' or burners 8, the object being to permit a'blank to remain on and. be revolved by the rolls 5 for a sufficient length of time to permit the burner 8 to preheat its center portion without delaying the operations that are subsequently performed on the blank and which will be described.

'lhereare revoluble rollers 9, of which eight are shown arranged in pairs and spaced from the rolls 5, and these rollers 9 receive and support blanks preheated on the rolls y5, while the blanks are worked on to draw them rapart and form bottoms on the separated kparts as will be presently described. llrom'the rollers 9 the finished bottles or vials are delivered to a chute 10 on opposite sides of a rib or partition l1. l2 is an arm provided with two sets of lingers i3 and la. rl`he fingers i3 serve to transfer the blanks from the rolls 5 to the rollers 9, and the fingers .lav serve to transfer two finishedvialsfrom the rollers 9 tothe chute 10, at the same motion of the arm, which is a comparatively quick motion, whilst the return of the arm to its initial position shown in Figure l is a comparatively slow motion,

'allowing time for the necessary heating of the glass.

The movement of the arm 12 referred to is yprovided by the slot 15 formed in it and against the back stops Starting from the position just preceding that shown in Figure 1 and when the element 17 is rotated in the direction indicated by the arrow in TFigure fr, the arm is lifted so that its `lingers 135 engage the blanks and its lingers 1'1- engage the iinished vials, and then the upperI end of the arm is turned toward the left with a comparatively quick motion. The arm then slides on the pin so that the lingers are lowered, depositing the preheated vials on the rollers 9, and the finished vials on the table or chute 10, and then the lingers returned to their initial position with a comparatively slow motion. ln consequence or this there is provided suiicient dwell `for preheating the blanks and "for forming the bottoms of vials, whilst the `feed oit the preheated blanks is rapid. i blank on the rollers 9 having been preheated on the rolls 5 is further heated by the burners 18, and at the same time is subjected to the action of the driven beveled rollers 19 which revolve the blank and tend to separate it at the center where it is heated into two parts as shown in Tiligure 8. The action ot' the rolls 19 also pushes the ends or the blanks rlhese rollers 19 are of rubber or other like material and are provided with beveled rims for the purpose described. The rollers 19 are mounted on the end of arm 2O pivoted at 21 to standards 22 and they are driven 'il om the shalt ,7 as by means of gearing 23. The arm 20 is connected by a link 2d and with a 'follower 25 that co-operates with a cam 36 on the shaft 7. il cam 26 operates a spring retracted wedge lever 27, which works in between the slides 33 that carrytthe pairs of rollers 9, and operates to push those slides apart against the springs 2S and to permit them to approach each other (see Figure 23). The cam 26 operating to shift the pairs of rollers 9 apart, causes the blank to be separated in the middle where the application or' heat assists in the separation, Fig. 9. Then the rollers 9 approach each other to bring the bottoms into 'the direct influence ot the llame to square them,

as shown in Figure 10. The rollers are again separated and whilst the rollers .j are separated the cam 17 which held the bottomer or blade 29 in the position shown 1 and e against the tension of' its in r spring 230 permits the arm 31 on the blade 29 to fall into the low part oit the cam 1T, thus driving the blade 29 between the ends oi'Y the sections oi the blank as shown in Fig. 11, whereupon the wedge device 27 is withdrawn and bumpers 32 adjustably mounted on the slides 33 are caused under the action of the springs 28 to press or drive the two sections or the blank against the blade 29 as shown in Fig. 1]., and in that way the bottoms ot the blanks are 'lessees completed. Cam 534% on the driven shaft Y pr vided with a lollower 35 which operates the gate rThe mode of operation orc the described machine may be explained as follows: Blanks are lied singly trom the hopper onto the rolls 5 where they remain long enough to be centrally preheated, while at the saine time blanks'on the rollers 9 are being cut in two and each part provided with a bottom. The 15 by the lingers 13 conveys preheated blanks from the rolls 5 to the rollers 9 and simultaneously the fingers 14 convey the iinished product to the chute 10 on each side oi the partition 11. rllhis is' accomplished with a quick motion of the arm and the return motion oi' the arm is comparatively slow so as to get time for the completion of the described operations. rllhe shitting oi" the slides 33, and the rollers 9 which they carry by the described wedgelike mechanism and springs 28, performs an important function in dra ving the tube into two parts and in subsequently bumping these parts against the plate 29. @if course the 'leed to the machine from the hopper in connection with the other features makes the nachine entirely automatic. lt may be observed that the end oi' the blade 29 is notched and this provides some spring for takin up the impact ot the bumpers 32 and it may also be said that the slides 33 are shown as movable crosswise of the machine on dove-tailed ways, Figure 1.

lt will be obvious to those skilled in the art to which the invention relates that modil ications may be made in details or construction and arrangement without departing from the spirit oit the invention, which is not limited as to those matters or otherwise than as the prior art and the appended claims may require.
